SEWING MACHINE GUIDE ATTACHMENT Filed July 13, 1948 INVENTOR. i?@2705627 52765202 fm2@ SVM Patented May 8, 1 951 OFFICE fservicio-MACHINE GUIDE ATTAQHMENT George Becker, Brooklsn, Y..application July 13, 194s, semaine. `33,447 i Q Vvide aguide attachmentadapted to be secured to -the sewing machine 'head ,about the Sleevethrough Jv hich the needle is extended and vwhich has guide membersadapted to be extended onto the material being stitched so as to provideguides between which the cloth or material is extended or maintained bythe operator While the stitching operation is being performed whereby astraight stitching line will be maintained at all times an equaldistance from the edge of the material and wherein a folded over hemwill be retained between the guide members while the stitching is beingeffected.

It is another object of the present invention to provide in a guideattachment for sewing machines angularly adjustable guide elements whichwhen not in use can be lifted and automatically retained in an elevatedposition and which will be retained in its lowered position againstspring action upon a square surface of the element retaining the guidearm.

Other objects of the present invention are to provide a sewing machineguide attachment which is of simple construction, easy to adjust, easyto rearrange for different operations, inex- I pensive to manufacture,rugged, compact, and

efficient in operation.

For other objects and for a better understanding of the invention,reference may be had to the following detailed description taken inconnection with the accompanying drawing, in which Fig. 1 is aperspective View of a sewing machine and of the attachment connectedtherewith with the guide arms extended into engagement with materialbeing stitched.

Fig. 2 is `a sectional View taken on line 2 2 of Fig. 1, but with theguide arms arranged in an opposing relationship as when the attachmentis being used to retain a hem which is being stitched.

Fig. 3 is a top plan View of the attachment with the arms arranged as inFig. l.

Fig. 4 is Ia side elevational view of the attachment with one of theguide arms lifted.

Fig. 5 is a fragmentary perspective view of the retaining springs forone of the guide arms.

Referring now to the figures, Ill represents a sewing machine tablehaving a sewing machine head II extending upwardly from the same andover the table. Depending from the head or y arbor is a sleeveprojection I2 through which needle I3 is operated. A thread I4 extendsto the needle. Upon this depending projection 'I2 -may be attached mystitching guide attachment I5. This attachment comprises a main body =I6having a split opening IIafor receiving the projection I2. A screw IBf-xes the Ibody to the projection I2.

Extending through the ,body are parallel threaded openings 2-I and .22for receiving respectively adjustable threaded sleeves 23 and 24 havingrespectively head portions 25 with at faces 26 and 2l thereon angularlydisposed from one another and against which may bear leaf retainingsprings 28, Fig. 5. Adjacent the face 26 is a shoulder 29 adapted tolimit the downward turning movement of the screw. Extending through eachscrew 23 and 24 is a guide arm. In the screw 24 is a guide arm 3| whilein the screw 23 is a guide arm 32. The guide arm 32 is larger than theguide arm 3l.

The guide arm 3| has a short shank 33 extending through the sleeve 24and a crooked portion 34 having a rounded foot or engaging formation 35thereon. In each head 25 is a set screw 36 for securing the shank of theguide arm to the sleeve, Fig. 4.

The guide arm 32 has a long shank 36 which is extended through thesleeve 23, a crooked portion 31 with a foot or engaging formation 38.The leaf springs are fixed to the bottom face of the body I6 by screws4I.

The guide arms 3| and 32 can be arranged as shown in Figs. 1 and 3 ormay be arranged as shown in Figs. 2 and 4 and extending from theopposite sides of the body I6. When the guide arms are arranged as shownin Figs. 1 and 3, their crooked portions will lie on the same side ofthe body and the engaging formations 35 and 38 respectively will lieparallel with one another on the same side of the needle I3. The outerformation 38 will preferably lie at the edge of cloth material as shownin Fig. 1 while the formation 35 will lie just inside of the needle andadjacent the stitching line as indicated at 45, Fig. 1. This formation35 will hold the cloth in place on the table while the needle I3operates beside it. The respective heads 25 of the sleeves will lie onthe respective opposite sides of the body I6.

With the arms down, shoulder 29 on head 25 will engage the side of thespring 28 and be prevented from further rotation in a down position. Ifit is desired to raise one of the arms, the same will be lifted upwardlyand the spring extended over the face 2l as shown in Fig. 4 whereby tokeep the arm elevated.

If the guide arms are arranged as shown in 3 Figs. 2 and 4, theformations 35 and 38 may receive a hem 41 of the cloth material M andthe hem may be secured by a stitching 48.

It should now be apparent that there has been provided a simple guidearrangement for sewing machines which can be easily adjusted between useand out-of-use positions without the necessity of having to use a toolor without having to loosen screws. The guide arms 3l and 32 can beeasily elevated from their down positions and will be automaticallyretained in their outof-use positions by the same springs which holdthem in their used positions. When one of the guide arms is not needed,it is simply flipped upwardly. The sleeves 23 and 2l being threadedwithin their respective openings to prevent the axial displacement ofthe arms when in use.

While various changes may be made in the detail construction, it shallbe understood that such changes shall be within the spirit and scope ofthe present invention as defined by the appended claim.

I claim:

A sewing machine guide attachment compris- -ing a main body adapted tobe clamped to a sewing machine head, said body having a threadedhorizontally-extending opening and a bottom face, a threaded sleeveextending through the threaded opening for pivotal adjustment therein,said threaded sleeve having a head portion with two flat surfaces angledwith respect to each other, a guide arm having a shank portion extendingthrough the threaded sleeve, means on the sleeve for locking the shankwithin the sleeve against rotational and axial displacement with respectthereto, and leaf spring means connected to the bottom face of the mainbody and extending parallel to the threaded sleeve, said leaf springmeans being engageable with the respective at angled surfaces of thehead portion, whereby to retain the guide arm either in its use orout-of-use positions.
